Specification of Letters Patent.

Patented Jan. 15, 1907.

knpiiczitinn filed fi ii; 17,1906. Serial No. 296,479.

lcmisylvaniii, have invented a new and improved Traction Device forVchiclc-i'lheeis, oi which the following is a. full, clear, and ex-:rct. description.

This invention relates to vehicleovhcc-ls and it consists substantiallyin thedctziils of construction and combinations of parts horn inattermore particularly described, an: pointed out in the claims.

Though applicable to vehicle-wheels generally the invention hasreference more esp"- cizillv to wheels for automobiles and the lilacinvolving the use of cushioning or pneumatic tires; and

slipping ol the wheel when the vehicle or mechinc being propelled oversoft or muddy ground.

A further object of the invention is to provide means for this purposewhich are simple in their embodiment as well as co mpara tivelyinexpensive to mzumfncturo and quickly ripplied and removed whendesired, besides pos:

sessing the capacity for long and repeated service.

The above and additional objects are zitj taiued by means substantiallysuch are 'illustra ted in the accompanying drawings, in which similarcharacters oi reference indicate corresponding parts in all the views.

Figure 1 is n side view of s vehicle-wheel having my improvements cm boded In con- 3 Fig. 2 is a view looking 1 nection therewith. at thestructure from the right side of Fig. 1. Fig 3 is a'perspective view ofthe tightenin ug, section of the device. view of one of the mainsections, and is a perspective ,view illust ruling in form of theinvention.

Fig. 5 tot l ici- Before proceeding Wibll a more detnilcd description itmay be stated that in the form of my improvements herein shown 1 employin connection with an ordinary vehiclewheel (preferably one providedwith a pneumatic tirc) n series of spccially-construct0d apartthroughout the circuuiicrcncc oi the wheel, said (lOVlCtS having spcrmll\'-con structed flexible constructions thorn-between,

by which to enable the some to conform to one of the principal objectsof the f invention is to provide means tor preventing Fig. i is asimilar l the rotary movements of the wheel and still l retain theirc'llcctive operative relation there l to. The de ices in question may besaid to constitute grips for taking into the surface and while I haveherein represented my improvements in 21 certain preferred embodiment itwill be understood, of course, that I m not limited thercto in precisedetail, since imnmtcrinl changes therein may be re- 1' sorted to comingwithin the scope of my invent ion.

licirrence beinghad to the drawings by he desigi Hing charactersthereon, 1 rep1retits :2 ve-iclc-whccl, prct'criibly provided at no rimthereof with n cushioning or pneumutic tire 2. Disposed transversely ofsaid rim and over or about the trend-sutface 3 of the stud tire 2- is nseries of my improved speciall v-const-ructed grips or traction devices,catch of which comprises an arched member 4, tot metal) of suitabledimensions; lying across the said trend-surface 3 and in suliicicntlyclose proximity therctopthe sides of said member being oi any desiredlength and extending in the direction of i i l l l ihe weer-llsubstnntinll as indicated in Fig. 1. l lilxi'ending iron] the side 5 ofeach of the l members -11, and preferably having threaded 1 engngcmcnttherewith at. 5, is :i connecting l member 6, having at one cx'rrcmitv ahook 7 l and at the opposite end no eye 8, projecting I it theoppositosi(le l i'oni the hook. This eye I cooperates with, n hoot; oilon adjacent coni nectiug member, thus joining ii series encirl clinglieWheel. Connecting the ends of the series at each side of the tire is adivided connectinc member comprising sections 9 1111(19, provided withm'ljnocnt angular extensions .10. in these extensions are o 'ieuings tore chive z'i (winner-ting and tightcmng bolt 11.

The outer end of each of the connecting members 9 and 9 has on eye anda- .hook similar to the main members and conctingtherewith. By thisconnection the grips or tram tion devices are maintained at the desireddistance apart relatively to the trend of the wheel or tire thereupon,While at, the some time the dost.-ribcdconnections therebetween I arellcxihlc, thus enabling the grips or tracf lion doviccs to clt'ectivelyoperate to dig into the surface ol the soft or muddy ground over whichthe wheel may be caused to move, l assisting the traction of the vehicleon which the whccl may be employed and also entirely preventing anyundue slipping of the of the ground traveled over by the wheel,

the axis of wheel either forwardly or reerwerdly of the motion thereof,all of which, it is thought, will be fully understood.

By means of the bolts 1 1 the degree of flexibility between the grips ortraction devices of the devices themselves may also possess e certainamount of resiliency, which, (LS is :11. parent, Will also be ofadvantage in. some instances. Y The devices may be quicklfepplied andremoved from the Wheel, and it will be understood that I am. not limitedto the dctails of construction thereof shown, nor to the specific formoi the couplings herein employed for flexibly and edjnstebly connectingthe seine together.

in Fig. 5 of the drawings I have illustrated another form of main memberin which an arched portion 12 is shown flattened and provided with acall: 18 to increase the grip of the device upon the supportingsuidece.

Hevingthus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A 'vehicle whe el provided about the tread thereofwith a. series of traction devices, each having connecting membersprovided at one end with c hook and the other end with an eye forcooperation faith the hook of a companion member.

2. A traction device for vehicllewhecls comprising a series of archedmembers errainged transversely oi the tire and having; their legsextending toward the axis of the wheel, connecting members arranged.upon each side of the Wheel, each of said members being comiccted withthe leg of en arched member, one end of each of said members beingprovided with en opening and the other with e hook for engaging theopening of an adjacent connecting member.

3. A traction device for vehicle-wheeis comprisin a series of archedmembers, the legs thereof embracing the tire, a connecting member uponeach side of the tire into which the ieg of the arched member isthreaded, said connecting members having at one end a hook and at theother end an eye for engage ment by the hook of the preceding member.

In testimony whereof I have signed. my name to this specification in thepresence of two subscribing Witnesses.
